Here are some bad habits before bed that can harm your health:
1. Mental Work Before Sleep
If you have the habit of working or studying at night, tackle more mentally demanding tasks first and save easier ones for later. This allows your brain to relax and facilitates falling asleep. Otherwise, if your mind remains in an excited state, you may struggle to sleep even after lying down. Over time, this can lead to insomnia.
2. Eating Before Bedtime
When entering sleep, certain bodily functions slow down to rest. Eating before bed forces organs like the stomach, intestines, liver, and spleen to work again, increasing their burden and preventing other organs from resting adequately.The brain region governing digestive functions also becomes stimulated, often leading to nightmares after falling asleep. If dinner was eaten too early and hunger arises before bedtime, a small snack or fruit (such as bananas or apples) may be consumed. However, allow at least half an hour of rest after eating before going to sleep.
III. Pre-Sleep Agitation
Human emotions—joy, anger, sorrow, and pleasure—can easily excite or disrupt the nervous system, making sleep difficult or even causing insomnia. Therefore, avoid intense emotions like extreme joy, anger, worry, or frustration before bedtime. It is best to maintain emotional stability.If you find it hard to fall asleep due to nervous tension or emotional excitement, lie on your back with your hands placed below your navel. Rest your tongue against the roof of your mouth, relax your entire body, and swallow saliva as it forms in your mouth. Within a few minutes, you should drift off to sleep.Speaking tends to stimulate the brain and activate thoughts, which can disrupt sleep. Therefore, excessive conversation before bedtime is inadvisable.
V. Sleeping Position
The optimal sleeping posture is lying on your right side. This allows the entire skeleton and muscles to relax naturally, facilitating sleep and alleviating fatigue.Sleeping on your back keeps your bones and muscles tense, hindering fatigue recovery. It also increases the risk of nightmares caused by arms pressing against the chest, which can obstruct breathing and degrade sleep quality.Sleeping with your mouth open makes you vulnerable to viruses and bacteria in the air. Not only does this allow illness to enter through the mouth, but it also exposes the lungs and stomach to cold air and dust, potentially causing illness. Seven. Sleeping with your head covered Some people habitually sleep with their heads covered. This causes them to inhale large amounts of their own exhaled carbon dioxide while lacking sufficient oxygen, which is extremely detrimental to health.Sleeping in a draft Avoid exposing your head or body to drafts entering through doors or windows while sleeping. During deep sleep, the body's ability to adapt to external conditions diminishes. Prolonged exposure to cold air can penetrate through the skin's capillaries, causing mild symptoms like colds or severe issues such as facial paralysis.
9. Sleeping Facing a Light Source
Even with eyes closed, the human body remains sensitive to light. Sleeping directly facing a light source disrupts the body's natural equilibrium, causing irregularities in body temperature, heart rate, and blood pressure. This leads to restlessness, difficulty falling asleep, and frequent waking even when sleep occurs.
10. Sleeping Near a Stove
This causes the body to overheat, increasing susceptibility to skin infections like boils. Getting up at night to use the bathroom also heightens the risk of catching a chill or developing a cold. Notably, if using a honeycomb coal stove for warmth, ensure proper ventilation to prevent carbon monoxide poisoning.
